About Jad
Solutions architect, team lead and senior systems engineer. I have spent more than twenty years making infrastructure faster, more reliable and less manual.
From dial-up to AI infrastructure
A relentless drive to automate, streamline and keep improving has shaped my career from the start. That start was the dial-up era of the late 1990s, at a family-run ISP in Sydney, where telecommunications and IT got into my blood.
The next two decades were spent close to the metal. I racked and ran colo footprints across multiple data centres, including NEXTDC and Global Switch; built, hardened and automated fleets of bare-metal and virtualised Linux servers; and ran the networks underneath them, from BGP and VLANs to firewalls, SD-WAN and thousands of VoIP and PBX clients.
That foundation is what I bring to cloud-native platform engineering and SRE today: fault-tolerant, low-latency systems on Kubernetes, AWS and modern infrastructure as code, and the AI-ready infrastructure that LLM workloads demand. I write the tooling myself in Go, Python and Rust, and I lead cross-functional teams to ship robust, scalable solutions that move the needle on performance, resilience and cost.
Along the way I learned that the hardest problems are rarely only technical. Leading the team, working side by side with the customer, and explaining a complex system in plain language, especially in the middle of an outage when the business is watching, matter as much as any configuration. I take that side of the job as seriously as the engineering.
How I work
Automate the second time
If a task has to be done twice, it gets scripted, versioned and reviewed. Across my career that habit has saved thousands of manual hours and removed whole classes of human error.
Measure before you change
Observability comes first: metrics, logs and alerts that tell you what is actually happening, so decisions about scale, cost and reliability are made on evidence rather than instinct.
Design for failure
Production fails in interesting ways. I build for redundancy, fast recovery and changes that can be rolled back, then write the runbook while the reasoning is still fresh.
Lead from the keyboard
I lead by doing the work alongside the team: pairing, reviewing, documenting and mentoring, so good practice spreads and outlasts any single engagement.
Make the complex simple
If the people who have to decide cannot follow the explanation, the explanation has failed. I lead with impact, use plain words and adjust the depth to who is listening.
Calm, clear and early
When the stakes are high, I communicate before I am asked: what is affected, what we know, what we are doing and when the next update will come. Then I keep that promise.
